snapshot

Go to: Related nodes. Attributes.

This node is used to evaluate an input geometry or matrix at a range of times defined by the "startTime", "endTime" and "increment" attribute values. When a geometry is attached as the input, the output is a sequence of time-evaluated geometries, which is referred to in maya as an "animated snapshot". When a matrix is attached as the input, the output is a an array of points that indicate the motion trail of the input matrix data.

animCurveChanged, endTime, frames, increment, inputGeom, inputMatrix, localPosition, localPositionX, localPositionY, localPositionZ, outputGeom, points, snapshotObject, startTime, update

Long name (short name)	Type	Default	Flags
endTime (e)	time	::zero
The last time at which to evaluate the input geometry
frames (f)	ticksArray	NULL
Stores the list of frame numbers corresponding to the points. The frame unit is ticks.
increment (b)	time	1film
How much time exists between copies of the geometry
inputGeom (in)	geometry	NULL
The input geometry
inputMatrix (im)	matrix	identity
The input matrix.
localPosition (lp)	double3	0.0, 0.0, 0.0
Offset position for the shape in local space coordinates.
localPositionX (lpx) distance (double) 0.0cm Local location in X.
localPositionY (lpy) distance (double) 0.0cm Local location in Y.
localPositionZ (lpz) distance (double) 0.0cm Local location in Z.
outputGeom (out)	geometry	NULL
The output geometry
animCurveChanged (acc)	Message	n/a
This attribute is used internally to store whether dirty messages received by the inputGeom attribute arrive from transformations versus modifications to animCurves that affect the snapshot calculation. This allows the most common case of snapshot usage (that of snapshotting an animated object) to work more efficiently.
points (pts)	pointArray	empty
Outputs an array of points that correspond to the locations of the translate pivot of the snapshotted object.
snapshotObject (so)	Message	n/a
This attribute is connected to the object we are snapshotting.
startTime (s)	time	::zero
The first time at which to evaluate the input geometry
update (up)	enum	1
Controls whether the snapshot updates on demand, or updates whenever the inputGeom attribute is marked dirty, or only update when an input animCurve is modified, versus every time the input shape attribute is modified. Note that we now 'always' update the snapshot values and so this attribute is obsolete
